Ive done a re-paste on mine with IC7 and the temps have stayed pretty much the same.

Ive since noticed that the fan doesn't spin any faster until the CPU hits 95c so re-pasting is only going to slightly delay how quick it heats up but its still going to reach 95c in the end, but at least it does cool a little quicker once it speeds up.

The only way you would notice a difference between factory paste and third party paste is if you control the fans yourself with SMC or Lubbos.
actually its under load that the paste matters, so yeah if you did this the right way, you will have an improvement regarding that.
 
That's the heatsink reading, not the cpu diode reading. The cpu diode could be +20 degrees from the heatsink when under load.

I think the difference would be closer to 10c than 20c, but even 74c (54c + 20c) is quite low at 100% load.

If anyone knows of another app for viewing the CPU temp, please let us know :).

UltraFan or SMC Fan Control 2.4 are accurate for Ivy Bridge, on the Retina`s your going to see high 90`s to low 100`s Centigrade under full load anything less is likely to be a error in software reading out the correct temperature or the system is not fully loaded.
 
I know they redesigned the cooling in the retina, but I wanted to change it to help out in any way possible.
You only "helped" yourself out of your warranty. :eek:

I've had a ton of people ask me to do this video, wether or not it changes a whole lot, people still asked for it so I did it.
I've always wanted to know if a rMBP can withstand a fall from 75 feet onto concrete.

All power to those that want to take the DIY path, equally doing this after the warranty period is the better bet. A good tech will know the machine has been opened up unless you are very competent in these matters, tool marks on screw heads are a dead give away for a starter ;) and as has already been stated you will make little or no difference to the operating temp of these new machines.

Exactly :p

I did this to help people, no need to get sarcastic. I didn't strip a single screw or leave any marks on them. No one will be able to tell I was in there :)

indeed, Ive always found that using a small piece of cloth wont mark the screws as well.

People its simple, the tech wont know. The paste is grey, like almost all the other pastes. If you dont strip or mark the screws you are good.

And yes it makes a difference apples paste application has always been bad, just because the fan profiles have such a large temp spam to engage doesnt mean that your cpu wont be cooler along your gpu.
 
Easy now, I've had bad experiences in the past so I took it into my own control and changed it. I know they redesigned the cooling in the retina, but I wanted to change it to help out in any way possible.

If you were being sarcastic then take this post as a sincere rebutle.

OK. It just seems a tad extreme.
 
What on Earth is the point of opening up a brand new, sealed laptop to replace the thermal paste? Are people just bored or something? What a nonsense.

I'm guessing you've never had a macbook that has overheated? the thermal compound used in ALL computers is a generic over the counter one. You can re apply newer nicer compound in order to lower temps, or slow the time it takes for it to reach max temp.

Again, this is an INSTRUCTIONAL VIDEO FOR THE PEOPLE WHO HAVE ASKED ME TO MAKE ONE. I'm pretty sure you guys dont give this much **** to the people over at iFixit...
 
Great video. I would do this if it was my laptop too.

HOWEVER:

You're still applying WAY too much thermal paste, and I can't believe nobody else has noticed this yet.

Most of that will ooze out the sides, just like the excessive Apple thermal paste does. Spreading a very thin amount over the dies with a thin piece of plastic will ensure adequate coverage. Those blobs are just way, way too much.
 
Or buy AppleCare.

Or Apple should be demanding their subcontracted manufacturer use proper quality grease in the first place. It's hardly going to hamper the profit margin, and if they did pass the sav... cost onto the customer, that extra $0.50 is hardly going to do any more financial hurt...

Yes I realized this too, it was bugging me since I did it, so I went back today, removed it all. Cleaned it. And re applied like a quarter of it.

Something to note: there's a little black plastic cover that sits around the outside of the processors, and I found A LOT of apples thermal paste under it. They used A LOT.

Thermal paste is pretty much the same with some brands being marginally better than others, and as with all, potentially there will be a trade off for that small margin. Large companies know this and tend to use generic thermal paste as it`s a good as anything else over time. The biggest difference being "smoke & mirrors"

I find 7c of difference quite meaningful. also you have to realize how to apply the paste. The latter makes a ton of difference as well.
 
Extreme to extreme is not meaningful at all, most thermal compounds will be in the middle ground 2C-3C at best including the bulk industrial. Application i do agree with

thats the thing, there are a lot of pastes in there and all are of good quality. even on boutique builders that difference is night and day when they paste it with a good paste instead of the one that came from factory, its a good 5-10c.

You only put numbers that pastes that are available to the consumer purchase dont make difference since the pastes itselves doesnt differ that much (which they do), you dont put the paste that was used at the factory, which are the ones that come in those pesky white tubes (extreme low quality if you used those), nor that the method of application makes any meaningfull impact, which it does.

I wonder how you will counter the old repasting threads showing the job that apple workers done when applying the past and the lowering of the temps due to the repaste.

Its simple, if you are inclined do it. Its worth it most of the times, including in this case

Thank you! Finally someone who agrees! :D

I don't need to it`s already been posted that one Retina owner did this and saw no benefit, older machines see the most benefit due to the cooling system being cleaned out, which is what i would expect for the majority. You can find posts both supporting and discounting, it`s simply a personal choice if you feel your system is running too hot. For posts supporting few will talk or take into account that as systems age the cooling system looses efficiency due to accumulation of dust etc. Cleaning the heat-syncs etc has by far the larger effect over replacing the thermal paste which may only bring a change of a couple of degrees.

Ive done a re-paste on mine with IC7 and the temps have stayed pretty much the same.

Exactly - not every machine out the box has issue with the cooling.

Not really as there is no pre & post values OP has no idea if any issue existed in the first place, my own Retina runs without issue including cooling, as likely does the majority of machines. Those that want to do this all power to them, just be mindful, you likely will not see the big changes that some are suggesting a few degrees at best...

Except that your rMBP never overheated. You barely even used it before doing this. I'm not knocking what you're doing, I'm just surprised that someone would open up such an expensive laptop to perform such an intricate surgery in order to avoid an overheating problem that does not exist.

Yes, while I did not test it I had read many users having warm keyboards and warm temperatures overall.

I've had macbook airs and pros in the past with overheating issues and have done this to both to correct it. I figured I would do it right away just to make sure. I know what I'm doing, I didnt break any seals, I didnt strip any screws and there was no marks of me being in there.

I did this video for those who requested it, theres a large group of people out there who have wanted a video like this, so I did one seeing as how I had already done it.

Heres a better way to apply thermal paste if you guys were wondering :rolleyes:

What tutorial video have you done lately? The OP just trying to help other people by using his own brand new rMBP. Rather than be thankful and appreciate the guy. You accuse him of being paranoid.

do link me to those please, the ones saying that paste replacement is a useless thing. its not.

If you want I can link you to high performance systems that there is a good measure of how effective a repaste is. Including mbps.

You also might not be aware that there is a complaint about the cpu and the gpu when stressed dont always use their thermal quota to the maximum, due to the high temps, and yes that is in the rmbp.

This is also good for overclockers.

you are not aware that those few degrees matters. For example in the 600m kepler ones (not all are kepler), there is a hard limit to what the chip can endure in terms of temps, its around 80c, thats when graphics start to fluctuate.

Also repasting in this model aint hard (quite the contrary, its extremely easy), repasting on the cmbp is another matter. I did it when the tech swapped the mobo, I hadnt the guts to do it before.
